Title: Liquid Fuel Injection Pumping Apparatus
Inventor: HUTCHEON KEITH FINER
IPC: F02M41/14
Filed: 1966-05-31
Abstract: 1,167,333. Fuel injection pumps. C.A.V. Ltd. May 22, 1967 [May 31, 1966], No.24086/66. Heading F1A. In a distributer type fuel injection pump having cam actuated plungers 12, a piston 21 loaded by a spring 24 and loosely disposed in a cylinder 20 is disposed in each of the outlets 17, the cylinder forming part of the flow passage to the line 18. The cam 13 is so shaped that after the end of each delivery stroke and whilst communication between the injection pump passage 15 and an outlet 17 is still established, a limited movement of the plungers in the filling stroke direction can occur followed by a rest period during which the connection between the passage 15 and outlet 17 is broken, whereby pressure at the outlet is relieved. As shown the piston 21 engages an abutment 33 in the rest position and the cylinder has ports 22, 23 communicating with the line 18. In a modification Fig.2 (not shown) the abutment is replaced by an annular valve seat on which the piston closes and the cylinder bore is enlarged to provide communication with the line 18 and is formed in a member with an end cap abutment for the spring 24 in place of the unitary member shown in Fig.1.

[Also in Group XL (a)] In apparatus, e.g. a nuclear reactor, where it is desired that the fluid flowing in ducts 1 which are arranged in a set of columns and rows C, R, Fig. 1, be periodically tested, e.g. for content of fission products, the ducts are individually associated with valves, the actuating means of which are arranged in a co-ordinate system of rows and columns. In the first example, Fig. 2, a common rotary or reciprooable valve actuator 4 is associated with each column C and a similar actuator 6 with each row R. A rubber tube 3 passes through each duct. Any duct 1 may be opened by actuation of the associated actuators 4 and 6. In the second example, Fig. 3, each duct 1 leads via the bore in a sleeve 15 to a testing conduit 8. Associated with each sleeve is a double piston arrangement 12, 13. A conduit 9 leads to the piston 12 and a conduit 10 to the piston 13. When fluid under pressure is supplied to conduit 10 the piston 13 is raised so that the closure pad 16 closes the associated duct 1 and when fluid under pressure is supplied to the conduit 9 both pistons 12, 13 are raised so that the associated duct 1 is closed. The conduit 9 and 10 are arranged in rows and columns so that if pressure is released from conduits 9 and 10 the fluid in the associated duet 1 moves the closure member 16 away from its seat to interconnect the duct with the testing duct 8.

Title: Improvements relating to the purification of metaphosphates
IPC: C01B25/445
Filed: 1936-09-16
Abstract: Alkali metal metaphosphates, for instance the sodium or potassium salts, are freed from impurities such as iron, aluminium, chromium, or vanadium, by treating their solutions with a soluble alkaline compound such as caustic soda, and filtering off the precipitate formed.  Slight excess of the alkali is preferably used, but insufficient to redissolve any aluminia precipitated.  The purified solution may be evaporated to dryness and ignited.  The metaphosphate may be obtained from a solution of phosphatic material in sulphuric acid by adding sodium hydroxide or carbonate to form a solution of sodium dihydrogen phosphate and precipitate a portion of the impurities, filtering the solution and evaporating it to dryness, and fusing the residue; or the sulphuric acid solution may be so concentrated that on addition of sodium hydroxide &c. the dihydrogen phosphate is precipitated in the solid form which is heated and fused without separation of any impurities.
